If you own a Frigidaire dishwasher, you expect it to make life easier, not add new problems. But seeing a strange code like “Pf” on the display can feel confusing. What does it mean? Is your dishwasher broken? Can you fix it yourself, or do you need a technician? Don’t worry—you’re not alone. Many Frigidaire owners encounter the Pf code at some point. This guide will help you understand what the Pf code means, why it appears, and the best ways to solve it—often without calling for repairs.
What Does The Pf Code Mean On A Frigidaire Dishwasher?
When your Frigidaire dishwasher shows a Pf code, it’s signaling a power failure. The “Pf” stands for “Power Failure.” This code appears when the dishwasher loses electrical power while running a cycle and then regains it. It’s a built-in safety feature, not a sign of damage or a broken machine.
A power failure can be caused by:
- An outage from your utility company
- A tripped circuit breaker
- The dishwasher being unplugged accidentally
- Brief power surges or voltage drops
After a power interruption, the dishwasher is unsure whether it completed its last cycle. The Pf code appears so you can check and restart the cycle if needed.
Common Causes Of The Pf Code
Understanding the root causes behind the Pf code helps you fix the problem faster and prevent it in the future. Here are the most common reasons:
1. Electrical Outages
Any loss of power—even a quick flicker—can trigger the Pf code. If your home has experienced storms, heavy winds, or grid issues, this is likely the cause.
2. Tripped Circuit Breaker
Dishwashers use a dedicated breaker. If the breaker trips, the machine loses power and will show the Pf code when power returns.
3. Loose Power Cord Or Plug
Sometimes, vibrations from the dishwasher or nearby appliances can loosen the power plug. If the plug isn’t fully seated, it may cause intermittent power loss.
4. Faulty Outlet Or Wiring
Old or damaged outlets can cause brief power drops. In rare cases, worn wiring inside the wall or the dishwasher itself can be the culprit.
5. Accidental Unplugging
Someone cleaning behind the dishwasher or moving kitchen appliances might accidentally unplug it.
6. Power Surges
Sudden spikes in voltage, often from storms or large appliances turning on/off, can trip the dishwasher’s power safety feature.

How To Fix The Frigidaire Dishwasher Pf Code
Most of the time, fixing the Pf code is simple. Here’s what to do:
Step 1: Confirm Power Is Restored
Check if the rest of your kitchen has power. If not, wait for the outage to end. If only the dishwasher is affected, check your home’s breaker panel and reset any tripped breakers.
Step 2: Press The Start/cancel Button
After power returns, press the Start/Cancel button on your dishwasher. This usually clears the Pf code and lets you resume or restart your wash cycle. If your model has a digital display, the code should disappear.
Step 3: Inspect The Power Connection
Unplug the dishwasher (or turn off its breaker for hardwired models) and inspect the plug and outlet. Make sure the plug is firmly inserted. If you see burn marks, loose wires, or a damaged cord, stop and call a qualified electrician.
Step 4: Restart The Cycle
If the Pf code is gone, set your preferred wash cycle and press Start. The dishwasher should run normally.
Step 5: Monitor For Recurring Issues
If the Pf code returns often or during cycles, it’s likely a sign of a bigger electrical issue.
When To Call For Professional Help
While most Pf codes come from temporary power loss, some situations require expert help:
- The Pf code appears repeatedly without clear cause
- You notice burning smells or see sparks near the outlet
- The outlet feels hot to the touch
- The dishwasher refuses to power on after clearing the code
- Other appliances on the same circuit also lose power
Don’t risk electrical safety. Persistent Pf codes can point to wiring problems, failing control boards, or other faults. In these cases, contact a licensed appliance technician or electrician.

How The Pf Code Affects Your Dishwasher
The Pf code is a protection feature. It helps prevent water leaks, soap residue, or unfinished cycles. But if left unaddressed, it can cause:
- Dishes remaining dirty due to incomplete cycles
- Water pooling inside the tub
- Unpleasant smells from standing water or detergent
- Interrupted scheduling if you rely on delayed start features
It’s important to clear the code and restart the cycle to ensure your dishes are properly cleaned.
How To Prevent Future Pf Code Errors
You can’t stop every power failure, but you can reduce the chances of the Pf code interrupting your wash cycles. Here are practical tips:
1. Use A Surge Protector
Plug your dishwasher into a surge protector designed for large appliances. This can prevent voltage spikes from causing power interruptions.
2. Check The Outlet Regularly
Ensure the outlet is tight and undamaged. Loose or old outlets are more likely to cause intermittent power loss.
3. Avoid Overloading Circuits
Don’t run too many high-power devices on the same circuit as your dishwasher. This can overload the breaker and cause it to trip.
4. Secure The Plug
Push the plug fully into the outlet. If your dishwasher vibrates during cycles, check that the plug hasn’t worked itself loose.
5. Keep The Area Clean
Avoid letting water, dust, or debris collect near the outlet or power cord.
6. Regular Maintenance
Have an electrician inspect your kitchen wiring every few years, especially in older homes.
Comparing Pf Code To Other Frigidaire Error Codes
The Pf code is just one of several possible errors. Here’s how it compares to other common Frigidaire dishwasher codes:
| Error Code | Meaning | Typical Solution |
|---|---|---|
| Pf | Power Failure | Restore power, restart cycle |
| i20/i40/iF0 | Drain problem | Clean filter, check drain hose |
| UO | Vent open | Check vent assembly |
| ER | Stuck keypad | Reset or replace keypad |
| CE | Control error | Check wiring, call technician |
Frigidaire Dishwasher Models Affected By The Pf Code
Not every Frigidaire dishwasher model displays the Pf code the same way. Most newer models with digital displays will show “Pf” clearly. Some older models may use blinking lights or beep patterns instead.
Here’s a comparison of how different series report the power failure:
| Series | Display Method | Typical Reset Method |
|---|---|---|
| Gallery | Digital “Pf” code | Press Start/Cancel |
| Professional | Digital “Pf” or blinking lights | Open/close door, restart cycle |
| Basic/Legacy | Beeping or cycle interruption | Power cycle, restart manually |
Always refer to your user manual for specific instructions for your dishwasher model.

Common Myths About The Pf Code
Many owners misunderstand the Pf code. Here are a few myths—and the real facts:
- Myth: The Pf code means the dishwasher is broken.
Fact: It usually means power was interrupted, not that there’s a fault.
- Myth: You must reset the dishwasher at the breaker every time.
Fact: Most Pf codes clear with the Start/Cancel button.
- Myth: Pf code always means a wiring problem.
Fact: Most cases are caused by simple power loss or unplugging.
- Myth: Only old dishwashers show the Pf code.
Fact: Many new Frigidaire models display this code after a power loss.
Knowing the truth helps you respond quickly and avoid unnecessary worries.
What If The Pf Code Won’t Clear?
Sometimes, the Pf code stays on the display even after you follow the normal steps. Here’s what to try:
1. Hard Reset The Dishwasher
Unplug the dishwasher from power (or turn off the breaker) for 5 minutes. Plug it back in and see if the code is gone.
2. Check For Water Inside
If there’s standing water, remove it with a sponge. Restart the cycle.
3. Inspect Control Panel For Sticking Buttons
A stuck button can confuse the control board. Gently press each button a few times.
4. Review Error History
Some Frigidaire models let you access error history by pressing certain button combinations. Check your manual.
5. Contact Support
If all else fails, call Frigidaire customer support or a local appliance repair service.
Real-world Example
Consider this scenario: You run your dishwasher at night, but a thunderstorm causes a brief power outage. In the morning, you see the Pf code. Your dishes are still dirty, and the cycle didn’t finish. You press Start/Cancel, select your wash cycle, and the dishwasher runs as usual. No tools, no repairs—just a quick reset.
But if you see the Pf code several times a week, and your other appliances also flicker, it’s time to check your home’s wiring or call an electrician. Small, repeated outages can damage electronics over time.
Quick Reference: What To Do When You See The Pf Code
- Don’t panic—the Pf code is usually not serious.
- Check that your dishwasher and kitchen have power.
- Press Start/Cancel to clear the code.
- Inspect the power plug and outlet.
- Restart your wash cycle.
- If the code repeats, consider electrical inspection.
